Cloud @ Scania - Södertälje Science Week
- 1. ANDERS LUNDSGÅRD, CS DELIVERY ENGINEERING / CLOUD ADOPTION - SÖDERTÄLJE 31/1 2019 Cloud @ Scania
- 2. 2012

- 9. Agile journey pre Cloud DevOps journey with Cloud
- 11. Why Cloud-first? • Innovation − High pace of new services from cloud providers • Speed − Microservices, DevOps, ease of use • Global Reach and availability − Global scale, many regions and availability zones • Security − Security functionality can be leveraged to reach a high level of security with minimal effort • Cost − Scale up and down, possibility to lower cost
- 13. 10 engineers 20 engineers 15 engineers 50+ engineers Scania Connected Services Message Platform Remote Diagnostics Fleet Management Tacho Does not scale!
- 15. • 3-8 people • Requirements • Technologies • Quality • Deployment • Monitoring • Operations 15 Autonomous Teams that fully own their services

- 17. Zero Downtime Enables engineers to be present when their code goes live
- 18. Deploy != Release Feature Team Concern Business Decision
- 19. Release
- 20. Release (Tilda 4 makes release with a one button click, 2016-10-01)
- 21. Deploy
- 22. Version Control Pull & Push several times a day Continuous Integration Server Target Servers (Dev, Staging, Prod) Version Everything Code Tests Configuration Database Pipeline Deploy Orchestrator Reliable changes must also include InfrastructureInfrastructure

- 24. Deploy frequency • 2015 – Agile teams • 12 deploys per year • 2016 – Autonomous Teams • Continuous Delivery • 30+ deploys per day • 2011 – Software projects • 2-3 in parallel • 3 deploys per year 1. Microservice Architecture 2. Trust and courage from management Continuous Integration

- 29. Supporting Cloud engineers What should they NOT DO? 29 Deployments
- 30. Cloud awareness Infra Dev DC-EXT Greenfield Dev Infra Infra Dev On-Prem Lift and shift EC2 RDS VPC Lambda DynamoDB Cloud awareness EB ECS You build it, you run it Message to Greenfield teams 1. Invest in Cloud education 2. Think long term maintenance - No patching of servers - Infrastructure as code!

- 37. Your Heroes are your Bottlenecks! Version Control Single point of failure Single point of knowledge
Editor's Notes
- It was the year of 2012… Me and a couple of engineers on a Meetup lunch saw this presentation…
- …an online shopping site named Etsy described how they produced software… This became a huge source of inspiration to us and has reflected the improvement work we made after that.
- …this was my desk on a Saturday morning back in 2012. Manual deployment to production that not only included me but also a couple of other engineers, project managers, etc…
- The cloud first decision (Q3 2016) was crucial for our cloud movement. No more ShadowOps!
- Slide from Jens Jensen. 1. We have turned the priorities upside down because we think innovation is the key to our survival

- 2+ servers (load balanced) No state on servers Live upgrade of Database schema
- Zero Downtime deployments. Deploy != Release Code review is your security gate. Not a QA or an ISec department.

- Moved from software projects to agile teams and continuous integration. Even with continuous integration and agile teams it is hard to maintaine a big codebase Also about 4 times more check-ins with the microservice architecture.
- Version Control hosted in cloud: VCS is like bread and butter: Free for everyone Enabled fully automation in AWS
